The teeth are a little loose, the treatment methods are as follows: First, you can take periodontal splints for loose teeth fixed, consider removing periodontal splints at 1-3 months, and generally the teeth can grow stable. Second, you can properly adjust the jaw teeth, reduce the biting force on the teeth, try to remove the ratio of crown to root ratio, so that the exposed part of the crown is as short as possible, which can alleviate the loosening to some extent. Third, periodontal surgery can be performed, and bone grafting can be taken to restore the height of the alveolar bone as much as possible. Fourth, the tooth can be fixed by using fiber band, but it is usually fixed permanently. Because most of the loose teeth are due to the resorption of the alveolar bone, it is difficult for the alveolar bone to recover completely.
